Follow these instructions if you are

•	using only one server to store user and group information
•	sharing user and group information with other servers, and this is the primary server

To configure Users & Groups on a primary server:

1	Open Mac OS Server Admin and log on to the server you want to configure.
2	Press the Users & Groups button and choose Configure Users & Groups.
3	Make changes to the configuration settings for failed logon attempts, password length, and password expiration.
4	Click Save.
5	Create users.
6	Create groups.
7	If you plan to share user and group information, use TCP Filter Admin to limit access to port 687 (for sharing user and group information) to only the secondary servers.
	To ensure security, block access to this port for other computers.
